SHEET-DISPENSING APPARATUS.

Application filed November 13, 1923. Serial No. $724,513.

This invention relates to sheet dispensing apparatus, and moreV particularly to coin controlled sheet dispensing apparatus. c

AnV object of my invention is to provide a coin controlled which is housed in a simple and convenient enclosure, that is easily and cheaply made, and is of sanitary and sturdy construction.

. Another objectof my invention `is to pro-v vide a strong supporting framework for sheet dispensing coin. controlled apparatus,

in which the assembly ofthe Aoperating parts on the framework is easily and quickly effected, to form a compact mechanism occupying small space.

A further object of my invention Ais to provide guides within the mechanism for properly directing a ysheet of vpaper in its course from a supply roll toV the exterior of the enclosure, thereby preventing possible bunching of the sheet material andV clogging of the machine. l c 1, Another object of my invention is to provide a mechanism which is simple and cheaply constructed,y and in which the operating.y parts are few in number and easily accessible for repair and replacement.

Wit-h these and other objects in view which may be incident to myimprovements, the invention consists in the partsl and combinations to be hereinafter set forth and claimed,

with the understanding that the several necessary elements comprising my invention,

may be variedin construction, proportions clearly understood, I have shown inthe accompanying drawings means for carrying the same into practical elfectvvithout limiting the improvements in their useful applications` to the particular constructions, which for the purpose of explanation, have been made the subject of illustration.

Fig. 9 is a sectional view in detail showing the operationof the feed and pressure rollers andthe cut-off mechanism. f

` In .the drawings I have shown a container `66 of Fig. 5looking in the direction of y or box for my mechanism having lai supportingbase 1 which. may be of wood. rThe `supporting base is adapted to be yhung against, or otherwisefastened to, the wall in a lavatory. vAttached to the supporting base l is a lower side 2 of sheet metal, having integrally formed ytherewith upstandingend pieces 3. The lower side terminates at either endyin headings twhich projectslightlybeyond a cut-out portion fat the front edge. The npstanding end pieces are formed with downwardly and forwardly. sloping edges 6, and upwardlyy i and rearwardly sloping redges 7, which terminatein cutoutportions l-through which an operating'shaft 9 to which an. operating handle 11 is attached extends.

Hinged to the lower side on a hinge pin l2` is an enclosing membery 13. The enclosing memberL 13 has la forwardly extending portion 14, which is in effect ak continuation of the lower side 2. At the point kof f juncture of the forwardly extending portion 14 and the lower side 2, in other words at the point of*` pivoting, the forwardly'extending portion has a `slot 15 cut throughthe sheet material to provide ay place for, the egress of the sheet from the machine.

, Integrally formed with theforwardly .eX- tending port-ion 14, and of the samev sheet metal, is an upwardly extending side 16, whose Lipper' portion is rounded, as indicatedy at 1 7. Above vrthe rounded portion y17 there is a horizontally extending portion 18 which `is suitably locked to .the supporting base l by means of a lock 19, that engages with a locking member 2l at the upper inner portion of the supporting base l. At the point where the curved portion i7 of the enclosing member commencesythere is provided a sight opening 22, through which the consumer can view the interior oitv the machine to sec ii? there is any paper' to dispense. On the side of the curved portion 17 is provided a coin slot 23.

integrally formed with the enclosing member are end pieces 2l which have downwardly and forwardly extending edgesy 25 adapted in the closed position to normally overlap, and extend parallel to,v the edges G of the'end pieces 3, and downwardly and rearwardly sloping edges 26 adapted in the closed position to lie parallel to,'and to overlap, the edges 7 of the end pieces 3. At the point oi2 meeting of the edge` 26with the edge 257 there is a cut out portion 27 through which the operating shaft 9 extends.

Mounted wit iin the box and attached to the supporting` base by means oi' suitable screws 28, are horizontally extending brackets 29 oit anglo iron te provide lightnr with great strength. The brackets are integrally formed with upwardly extending support arms 3l having llshapedfbearings 32 adapted to receive a shaft 33 of a supply roll 34.

Integrally formed with the brackets 29 are downwardly extending support arms 35 having bearings 3G formedtherein, in which is journaled a shaft 37 of a leed roller 38. The supporting brackets 29 are formed with horizontally extending arms 39, whose e5;- tremities are joined together by a joining bar'lll which holdsthe vtwo brackets vtogether, and which acts as a. pivot for the pressure roller support. to be later describedl The downwardly 'extending support arms 35 are formed with ardly and downwardly extending portions 42, in whose .extremities are pivoted abar d3 to which is attached the cut-oit mechanism, to be later described. Vertically oownwardly extending 01T set portions del serve supports to which are fastened parallel sheet guides l5 by means of a screw d6. Spacing inserts 47 at either end of t le parallel guides serve to space these guides apart. The guides are so locatedthat the paper easily passes between them without much friction. A plane tangent to the feed and pressure rollers at their points o't contact with -each other would ordinarilypass between the guides without touching them.

A sheet li3 from the supply roll 34 is adapted to be `led over the feed roller 387 and bet reen the feed roller 38 and a pressure roller i9 mounted on a shaft 5l journaled in supporting arms 52, whose other ends are pivoted on the joining bar 4l, thus permitting` the pressure roller to be swung lmember 7d.

r29 at 75and to the support member 67 at on the joining bar 4l as a pivot. Attached tothe supporting arms 52 are pins 53, to which are attached links 5l, which' are in turn attached to helical springs 55. The other ends lof the helical spring-s55 are attached to pins Afastened to the supporting brackets at 57. The springs 55 pull the )res sure roller i9 against the feed roller 38.

rlhe feed roller 38 may be et roughened exterior or of rul'iber, and the pressure roller may be' of rubber or any other suitable material. The paper -l-S is pressed tight against the feed roller and its rotation feeds the paper between the guides e5, and out through thedis'pensing slot l5. A plete guide 58 is located above and adj acent the point of contact of the pressure roller with the feed roller. The guide is inclined so that its lower end tends to press the paper i8 against the surface of Jdie feed roller, and prevents crumpling of the paper between the rollers, since it will tend to smooth ont folds in the paper sheet'at this point.

To cause the feed roller to revolve, the shaft 37 has keyed to its end a pinion 597 which meshes with a larger pinion Gl. The pinion 6l is keyed to a `cellar62 journaled on the operating shaft 9. The operating shaft 9 is journaled at one end at (i3 in one oli' the brackets 29,` and a washer 64j held tothe sha-ft 9 by means of a screw 65, tends to hold the shaftin position. The shaft 9 passes through a bearing 66 :termed in a support member 67, which is fastened to the joining bar eil' at one end, and at the other end to a small joining bar 68 fastened to the bracket 29 at 69. i Mounted on the collar G2 is a locking disk 7l havingy a locking aperture 72 therein for engagement with a projection 73 of latch vrrlhe latch member 7d is pivoted on a joinine' bar 75 connected to the bracket rlllieA latch 7d is formed with a recess 78 in its ent uthrough which passes the end of a helical tension spring 79 that is attached at its other end to a pin 3l Ltastened to an end oftheV horizontally extending arm 39." The projection 73 et the latch 74tis thus kept pressed within the aperture 72 on the locking disk.

Keyed to the sha-it 9 is a coin :feedingV disk 82. The coin feeding disk 32 is provided with a korf 33 therein'which normally lies adjacent the lower endy Se oi"- a coin chute connecting with the coin slot 23 in the casing. The kerl' 33 receives the coins which are prevented :from `falling out of the kerif by contact with a guide plate 8G, formed by the co nat-ion et the coin chute 85, and by a retaining pla. Jve 87, which is riveted te one side of the ree ling fdisk adjacent the kerl. rlhis retaining plate eX- tends laterally .ire-in the itace or" the coin fee-ding disk and is adapted to cofoperate llU fai

With a lug 88, onthe locking disk 71, to move the locking disk when it has been unlocked.

The coin feeding disk 82 is tornied with ratchet teeth 89 thereoinand Wit-h a smooth space 91. A pawl 92 mounted on the bar ll1 is held pressed against the ratchet teeth hy means ot a helical springY 93, mounted on the bar 41; One end ot thespring :93 engages Athe support arm 39 and its other endv passes through an aperture 9d1 inthe ypaivl 92. The latch 741- is provided with a sloping cani 95 adapted to engage with a coinin the kert 83 of the coin feeding disk. A spring 96 is'connected at 97 with the coin feeding disk and at 98 with the locking disk.

Then-a coin'is ted into the coin slot 23, it passes through the coin chute 85 and into the kert 83 ot the coin feeding disk,` 82. The handle 11 is rotatedin a clockwise direction and the rotation yoit the shaft 9 causes the coin feeding disk to rotate to a position at which the coin engages with the sloping surface oi thev cam 95,.' This causes the latch 74 to rise against the tension ot' the spring 79, thereby removing the projection 78 on the latch trom'the locking' aperture 72 onr the locking disk 71.y .Atthis time the pro- 'jecting retaining plate 87 on the coinl 'feeding'diskcomes in contact with the lug'88 on fthe locking disk, and the lockingdisk rotates with the coin teedingdisk. The coin passes onward vand drops into acoin box 100, as indicated by dottedlines in Figures 1 and y6. The locking disk con tinuesy its.rotationwith the coin feeding disk, and the rotationfof the locking diskk causes the pinion ,'61 to revolve, which in turn revolves the pinion 59 and turns 'the yteed roller 38 to feed torwardthe paper.

The paivl 92 prevents the return. 'ot Vthe coin feeding disk vuntil a revolutionhas been completed, at which timethe spring 79V pulls the latch 74: downward, fitting projection 7 3 intoftlie aperture 72 ofthe locking' disk. This-position is not reached, however, until the coin 'feeding disk lhas,completed slightly more than one turn. Once the locking disk is again enga-ged hy thelatch,

it can rotate nov further and the spring" 96V eonnectinigthe lockingdisk to the coin eeding; disk causes the coin feeding` disk to ro-i tate backward, the paWl 92 sliding over the smooth surtace'91 on the coin feeding disk.V The apparatus is then in position tor `another action. Y

1n the meantime,` however, the .cut-oit mechanismy toi' cutting olli' vtime sheet has been in operation, as Will nou/,he described. Attached tothe shaft 43 is a lever yarno 101. lThe lever arnr101fis-adapted to he oiierated by. means 'of a link 102 that isv pivoted to the end ot the latch 741. When the latchv is in the down position, as .shown Y in Fig. 1, `the leverarm 101 is in thek posichine and the latch /l is raised ythrough link 102levei' 101 is nlsoraised and thiscauses the shaft torotate, removingn thefeutter 105 `treinak-cross the opening atthe hase of the guides #15.* l s By reason oit the tact that therev is but one locking aperture on the locking disk, the projection 73 on thelatch 74; rides on the periphery ot the disk until one rotation has rheen completed.. To 4ride on the periphery ot the locking disk 71, the latch'inust neces sarily he in the upposition and hence the cutter duringI` the-rotation ot the feed roller permits 4,the passage ,of the paper.r kWhen the projection 73 on the latch .74 slipsinto thelocking aperture on the periphery ot the locking; disk 71, the spring 79 'forcibly pulls the link `102 downwardly, and through lever 101 and arins`103, the cutter y105 is made to cut kott the sheet ot paper 48. i

The operation ot the coin feeding` ldisk and paper `teeding,"mechanism and the cut-oil7 inechanisniis', ot course, simultaneous., that is to say, insertion o'fa coin and movement ot the handle 11 in a clockwise` direction, raises the latchk 711, unlocking the locking disk, and simultaneously'renioveslthe cutter 105 from its lpositionacross the opening` at the base oi the guidesy 45. The parts ot the cut-oilf` mechanism lare rheld in this position during'the entire rotation ot the locking ieoA disk until simultaneously with the lock'- y ing oi the locking;r disk, the cutter 10c'uts ott the sheet.`r The 'resilient connccting means, comprising` the 'spring 96 which lis iio connected at one end toy the coin feeding disk 82 and at the other end to the locking` disk 71, causes the coin teeding disk to yreturn to"ope`"ative positionfwith the kerf 83' directly adJacent the lower end 8st ot the coin chute S5. y

Supposethat the previous `usenhas torn ott onlya portion ot the sheet to which he isyentitled.' *.The'coin feeding disk will be heid bythe pawl 92511 somefposition other than its staitinfY position, Then kanother "coinis deposited,` this will not prevent the proper functioning ot the ,device, nor will the userlose his coin, since the coin reedingj disk can rotated to complete its partially completed rotation, and [the remainder et.

the sheet" will he. ted through the feeding .slot 15; `LrNot until the operation started by the previous userhas heen completed `Will the new vvcoin tall into place, andv then a complete reyolution of the feeding' mechanism can be made and an entire new sheet fed out. 1

The framework for the machine which l have devised is exceedingly strong and simple, and provides a. very compact mechanism which havehoused in a container especially adapted to my machine. The disposition of the paper guides and their functioning, tog-rether with the generally compact and efficient assembly render thismachine very sturdyy L d simple in construction.

While i have shown and described the preferred embodiment of my invention, l Wish it to be understood -that I do not coniine myself to the precise details of construetion herein set forth by Way of illustration, as it is apparent that many changes and variations may be made therein, by those skilled in the art, Without departing from the spiritl ofthe invention, or exceeding the scope of the appended claims.
